Specification of Letters Patent.

Patented May 2, l'lllli Application filed June 30, 1910. Serial No. 569,814.

To all whom it may concern: l

Be it known that I. Srnrnnx H. .lnowx. a

'citizen of the United States,,rcsiding at Rust in the county of Contra Costa and State of California, have invented a new and useful Separator, of which the following is a specification.

This invention has reference to improve-- ments in separators and its object is to pro-- Vide a separator adapted for extracting metal from mixtures of metal with ashes 0i dirt or sand, especially such mixtures as ac cumulate in brass foundries and smelting works.

In accordance with the present intention there is provided an inclined separating; table or receiving trough mounted on a 1-oclting support and means whereby a reciprocatory movement is imparted to the table by an eccentric or an overhead shaft.

The invention will be best understood from a consideration of the followingdescription taken in connection with the accompanying; drawings forming a part of this specification, in which drawings,

Figure 1 is a side elevation of the sepa 'ator; Fig. 2 an end elevation on a larger scale shoving; the upper end of the taoieg Fig. 3 is a plan view of the scparator on substantially the same scale as Fig. 1; his t is a detail sectional view of a portion of the bottom of the table on a larger scale than in the other views.

Referring to the drawings there shown a frame 1 whichlnuy be of general rcctangular shape and may be ll'lrltltlf of structural metal, suitably, braced, and the top menibcrs a of this frame are inclined in-thc di rcction of the length thereof so that one end of the frame is higher than the other. Mounted on the frame 1 are substantially triangular side extensions 52 rising: rather abruptly from the higher end of the frame 1 and sloping gradually toward the lower end thereof. At the higher end of each side on tension 2 is a bearing 3 for a shaft 4 constituting the power shaft of the machine, and this shaft 4 carries tight and loose pulleys 5, 6. There is also mounted upon the exten sions 2 a belt shifter '2' which. however. being of ordinary construction. needs no further description, it being designed to direct a suitable power belt to the pulleys and 6.

Traversing the frame l above the top longitudinal members i thereof near the two ends of the frame are rock shafts 8-9. ench carrying at the ends uprightnrms 10 pro vided at their outer ends with bearings for pins 11 projecting from an inclined trough or table 12, the arms 10 constituting support inn" means for the table 12 and causing the table when reciprocated in the manner to be described to travel an up and down direction as well as a longitiidinal direction, the up and-down direction being determined by the length of the arms 10 and their travel about the axes of the shafts 8 and 9.

The table 12 comprises a rectangular frame formed of longitudinal side members 13 and cross beams 14, the latter being suiiicicnt in number to make the structure rigid. The bottom of the table is in part formed of metal sheets l5 formed with a series of cross corrugations 16, each with an inclined face itlll'lilltillllg in an abrupt. face 17 where joining the next corrugation in order, the faces 17 being perpendicular to the plunc of the bottom of the table and directed toward the upper end thereof. 'lf'ho corrugated plates may extend substantially throughout the bottom of the table, or only partly thercorer, part of the bottom of the table being formed of plane sheets or plates.

Secured to the higher ends of tho extensions 2 are ln'ackets il desi forated pipes 19 no he ier end of the table and overhanging the bottom of the table with the perforations of the pipes direeled toward the said bottom of the table. These pipes are fed by other pipes 20 with interposed valves ill so that. 'atcr may be directed through the pipes 19 onto the sur face of the table or cut oil" tl'icrefrom at the will of the operator. The pipes are located near the upper end of the table so that water may be there directed to Flow down the inclined table by gravity and finally discharge from the lower or tail end thereof.

The shaft 4 carries eccentrics near opposite sides of the table at points substantialiy over its edges and the bands 220 of these eccentrics have screw sockets 240 which are connected. by rods 23 to screw soclrets 9 1 each connected by a spring plate or strip to the top of the respective side member 18 of the table 12 at :1 point between the pins or studs 11 connecting the table to the arms The rods 23 are threaded right and left at the ends so that they may be utilized as taltcups for adjusting the relation of the eccentrics to the table 12, the distance between the eccentrics and the elastic strips being shortened by turning the rods'23 in one direction and lengthened by turning ill) them in the otherdirection while lock nuts 26 on the rods 23 serve to lock these rods in adjusted positions.

0n the outer side of each side member 13 at a point between the pins 11 is a hook 27 to which is attached one end of a spring 28 preferably in the form ofa dual spring, While the other end of the spring is connected by a screw rod 29 to a bracket 30 on the corresponding portion of the frame member. 2. The screw rod 29 provides a 'means'whereby the normal tension of the spring 28' may be adjusted at will. The springs 25 tend to move the table. toward the lower end of the] frame 1 against the action oitthc springs'28.

At the upper end of the table 12 there is formed a pocltet 31 designed to receive the cleaned material and direct it to a suitable: .point of deposit. On top the side members 13 and extending between the same is a plate 32 upon which the 'material to be cleaned may be deposited and from which the ma:

terial may be fed onto the table surface 15.

' Let it be assumed that the machine is in operation by power applied to the pulley 5 by a suitable belt and that theshaft dis rotating at an appropriate speed, which speed in practice may approach ilVQ'lllllldl'Qd revohit-ions per Ininutethus imparting to. the table 12 a reciprocatory rockingmovement in an-arc about the axes of the shafts 8 and '9,- m'otion being transmitted to the table springs 28 so thatthc movement of the table is practically uniform in both directions.

- 'The mixture of metal with waste material such as-dirt or ashes (ir sand is deposited on the plate 32 and falls therefrom .onto the bottom of thcltablc where it comes into on I gagemcnt with the corrugations'16. At the same time wateris' admitted by way of the pipes 19 and gravitates down the bottom of the table toward thc tail end thereof. All

floatable material is at once carried ofit by the water while the lighter materials are eventually propelled by the water ,toward' the lower end of thetablel The heavier materials consisting of metal particles, which may range from metal pieces weighing a pound or more to emery grindings, lodge in the corrugations 16 against the shoulders 17. he movement ofthe table in a direction toward the upper end thereof will carry the heavy metal particles withit, while the return. movement will cause the relative movement of these metalparticles along the nomical.

an cement the inertia of the metal particles, andthe extent of movement with relation to the length of the corrugations in the direction of travel issuch that these particles will -movefrom corrugation to corrugation .to-

ward the upper end of the table to be ulti mately brought into the pocket 3].- and from thence discharged into a suitable receptacle by, gravity.

The particles of waste material are lighter than the metal to be saved and these 'particles even though comparatively heavy have insufiicient inertia to prevent them when the return'movement of the table occurs from being carried toward the tail endoit' the table,

by the down rush of water; In this man nor the metal is very thoroughly cleansed as has been demonstrated in actual practice inclined er the corrugations 16 due to I with a machine constructed as illustrated in uantities 'of metal such as foundin brass oundries and smelting works :maybe cleansed from ashes and dirt and sand and the metal" thereby recovered, the process tak ing but little power and proving very eco- The speed or the table and the relation thereof to'the drive shaft may be readily adjusted and determined as the character of the drawings, and it is found that large the material to be cleansed warrants, and the flow of water is also readily controllable by a proper manipulation of the valves 21. s

The plates 15 may be of suitable non c'or rodiblo metal such asgalvanized iron and l a may be supported directly each upon a'rubber -belt 33 What is claimed is 2- side bars, triangular frame extensions secured thereon with their higher ends ad-g jacent the high ends of said bars, transverse rock shafts on the fram'e'njear each end and 100 In a separator, a frame having inclined each provided with upstanding arms, an inv clinedtable carried by the upper ends of the arms, springs connected at their'upper ends to the side" bars of the frame and attheirQ I lower ends tothe table to oppose gravitating movements of the table, a drive'shaftjonr naled across the high cnds oisaid eXten- Y sions above the table, eccentricson the drive i shaft, bands on said extensions, and connections between said bandsiaiid-pointa on the sides of said table lower 'than'tlie position of said drive shaft.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
